1. There are chemical precursors to life on other planets — the same one’s that could have kickstarted Earth.
While the origin of life on Earth can still be debated among the scientific community, new findings suggest that the first traces of life on the planet over 3 billion years ago could be attributed to organic chemical reactions, according to Live Science.
The study, presented in January 2013 at a meeting of the American Astronomical Society, broadly concludes that life could originate from complex organic compounds formed within gas, dust, and plasma-filled interstellar clouds. As a result, these chemicals were then deposited onto Earth in the form of asteroids and meteors — which hit our planet much more frequently in Earth’s infancy.
